Checking eye pressure has come a long way — from the hand held Tonopen that allowed practitioners the ability to take checking eye pressure out of the exam chair (and even to screenings in nursing homes or hospitals) to the iCare tonometer with which doctors can obtain intraocular pressure readings without the need for numbing agents.  The newest player in the world of non-invasive tonometry is the Diaton tonometer by DevelopAll which allows doctors to obtain intraocular pressures for the first time through the eyelid, without need for drops or any contact with the cornea (where other ophthalmic tonometers need some type of contact, either with a probe or a puff of air).

Diaton Tonometer – Tonometry Through the Eyelid by DevelopAll Inc

Because the pressure is assessed through the upper eyelid, clinical studies report that it is ideal for use in pediatric patients, patients with corneal issues or after surgical procedures, and even after ocular traumas when eye pressure can be so telling about orbital penetration but is very difficult to obtain.

Some of the perks of the technology (in addition to being the most non-invasive tonometer on the market for patient comfort) include that there are no consumables involved in the use of the machine — no need for disposable tips or intensive sterilization protocols because there is no contact with the cornea or conjunctiva.  

Today, with infection prevention being a concern, Diaton tonometer is a leader in a Safer tonometry solution for IOP measurements.

Diaton Tonometer brings an added ability to measure intraocular pressure with contact lenses or scleral lenses on the eye, where the lens does not affect the accuracy of the IOP results.

Studies showed that there is a need for IOP measurements while scleral contact lenses are on the eye as IOP might elevate as much as 10 mmHg.

Diaton tonometer intraocular pressure IOP results are not affected by corneal biometrics.

With addition of transpalpebral and transscleral Diaton tonometer to the market, eye care and healthcare professionals now have an option to obtain IOP completely independent of the corneal biometric properties such as corneal thickness or thinness (CCT), post keratorefractive surgeries, LASIK, patients with keratoconus or any other corneal abnormalities.

Who uses Diaton Tonometer?

Diaton Tonometer is intended for use by Ophthalmologists, Optometrists, Ophthalmic technicians as well as Inpatient & Outpatient Clinics such as Hospitals, Emergency Department / Emergency Room, Urgent Care Clinics, Nursing & Elderly Homes, General & Specialty Practitioners as well as for Mass Glaucoma Screening purposes and medical missions.

Non-corneal, Scleral Diaton tonometer is particularly useful in cases where standard direct applanation (corneal) tonometry is difficult or not viable, such as with pediatric patients, in presence of certain corneal pathology, edema, infection, following corneal surgery, keratoconus, KPro and in cases of eye trauma.
